Photolysis of clethodim herbicide and a formulation in aquatic environments: Fate and ecotoxicity assessment of photoproducts by QSAR models.

The photochemical fate of the herbicide clethodim in natural waters was investigated under simulated and natural sunlight radiation. This herbicide exhibited a rapid degradation rate in simulated aquatic environment with half-lives ranged from 27.9min to 4.

Photodegradation behaviour of sethoxydim and its comercial formulation Poast under environmentally-relevant conditions in aqueous media. Study of photoproducts and their toxicity.

Photolysis is an important route for the abiotic degradation of many pesticides. However, the knowledge of the photolytic behaviour of these compounds and their commercial formulations under environmentally-relevant conditions are limited. The present study investigated the importance of photochemical processes on the persistence and fate of the herbicide sethoxydim and its commercial formulation Poast in aqueous media.

Atorvastatin decreases stearoyl-CoA desaturase gene expression in THP-1 macrophages incubated with oxidized LDL.

Statins, inhibitors of HMG-CoA reductase, reduce plasma low-density lipoprotein (LDL) cholesterol levels decreasing the incidence of coronary events. However, the observed benefit of statins appears to extend beyond their lipid-lowering effects. Previous studies by our group have demonstrated that atorvastatin in oxidized LDL incubated macrophages modifies the gene expression profile of certain enzymes involved in fatty acid metabolism, mainly stearoyl-CoA desaturase (SCD).

[Sensitivity and specificity of metabolic syndrome criteria for insulin resistance diagnosis in Spanish population].

Background And Objective: Metabolic syndrome (MS) is an abdominal obesity and insulin resistance (IR)-related syndrome associated with a high cardiovascular risk. Recently, the International Diabetes Federation (IDF) has proposed a modification of the Adult Treatment Panel III (ATP III) diagnostic criteria. However, the sensitivity of these new criteria has not been established.

Ultrasonography for the evaluation of visceral fat and the metabolic syndrome.

Association between abdominal obesity and cardiovascular disease has been related with visceral adiposity, through the predisposition of developing type 2 diabetes mellitus and metabolic syndrome (MS). Sonography is a simple and reliable method to measure both subcutaneous and visceral fat. To analyze the relationship of anthropometric measurements with abdominal adiposity measured by sonography and to analyze the utility of sonography in the prediction of insulin resistance (IR) and the other components of MS.
